1 Claim. (01. 220-10) My invention is an improvement in metallic receptacles such as barrels, drums or the like and.

relates more particularly to insulated metal barrels for storing-and shipping liquids.

One of the objects of the invention is to construct a metal barrel of inner and outer shells spaced from each other intermediate their ends, which when so assembled are adapted to-readily receive spaced inner and outer heads or bottoms which-may be welded or otherwise quickly secured in place.

Another objectof the invention is to provide an insulated container of this type which is rugged, sturdy and durable, and which is particularly well reinforced at the head and bottom portions, while simple of construction and assembly.

A further object of the invention is to..construct an insulated container of this type which is inexpensive to manufacture, yet which is capable of retaining liquids or other contents at or near the temperatures desired.

S A still further object of my invention resides in providing a fulldraining insulated metallic container. V

e Other objects and advantages of my invention will become more apparent from the following description of one embodiment thereof, reference view illustrating aform showing the constructionand assembly .of the head or bottom.

My invention relates particularly tosheet metal containers such as barrels, drums, or the like, of the insulated type, that is, having spaced inner and outer shells or walls which may provide a dead air space therebetween or which may be packed'with heat insulating material. The present embodiment will be described as one employing dead air spaces between the inner and outer walls. The invention, also relates to simple and inexpensive head and bottom structures, also of the insulated type. which can be quickly and msgeduess of the barrel as a unit. I

In carrying out my invention, I provide an innershell I and anouter shell 2 which are telescopically fitted together as illustrated in Figure 4. These shells are bowed outwardly as at l and 4 respectively, intermediate their ends, the ends terminating in cylindrical walls I and! respectively. The bowed portion 4 of the outer shell is formed on a longer radius than the wall 3 and when the shells are assembled as shown there is provided a dead air space I between the shells ex tending around the barrel and lengthwise of the same to the vicinity of the ends.

The end cylindrical walls 8 and iit closely together at the head and at the bottom of the barrel and provide a bore in'each end of the barrel for receiving the head or bottom members.

In the 'present embodiment the head and bot- --tom are indentical inconstruction, each comprising members t and l telescoped one within the other toprovide a dead air space I I between them, the annular flanges I I and if of these heads being in contact with each other and fitting closely within the inner end walls of the shell I.

In assembling a barrel embodying my inven-v tion, the outer shell may be rolled into bilge form, I-

the ends being cylindrical in cross section. The inner-shell may be formed first with a uniform diameter throughout and then inserted into the "outer shell, the bowed-portion being rolled subsequent to its assembly.

The usual bung ring I! may be iltted into open- I ings formed inthe shells I and 2, and securely welded or otherwise secured in place as at II.

, in one of the heads by' fitting a ring It 'in,aligned openings in the head members 8 and 9 and securely welding or otherwise fastening it in place as at It inexpensive insulated ba'i'rel or other container,

which is extremely rugged and durable; and which easily assembled and which greatly increase/the will permit rapid production due to the ease with.

. Likewise a filling; opening I! may be provided if I which it may, be assembled. Furthermore the 55 Itwillbe seen that I have provided a simple,

device is particularly well adapted to manufacturim methods. especially those employing sheet metal 1: in be understood that the embodiment of my invention shown is merely by way of illustration and that various changs may be made in the details of construction and arrangement of e parts without departing from the spirit of the drical wall portions between said rings and said bilged portion, aninner shell having cylindrical walls constituting the greater portion ,of its length and a substantially central bilged portion, the end walls of said outer and inner shells being closely iltted together and terminating in substantially the same transverse plane, end closures for said inner shell, said end closures each comprising a pair of'spaced covers each having vertically extending cylindrical flanges adapted-to fit snugly within the respective cylindrical ends of said inner shell, and each terminating in the said transverse plane oi. the end walls of said outer and inner shells, and a common bond for the respective end walls or said shells and said flanges whereby said bonded shells and. covers form heavily reinforced end structures {or said drum.
